Summary: | To compare the evolution of standard base excess and serum lactate level between surviving and non surviving patients with severe sepsis and septic shock resuscitated with early goal-directed therapy.
This is a retrospective study in an intensive care unit of a university tertiary hospital where 65 consecutive severe sepsis and septic shock patients were observed without any intervention in the treatment by the authors of this report.
In our study, the mortality of severe sepsis and septic shock patients was 38%. The central venous oxygen saturation of both groups was above 70% after the resuscitative period, excluding the second day of the non survivors group (69.8%). After the second day, the central venous oxygen saturation was significantly higher in the survivors group (P < .001). Standard base excess was initially low in both groups, but from the second day on, the correction of standard base excess was significantly more successful and linear in the survivor group (P < .001). Lactate levels were similar during the evolution of both groups.
Although evolutive standard base excess and serum lactate level are still outcome markers in severe sepsis and septic shock patients resuscitated with early goal-directed therapy, other studies must be performed to clarify if hemodynamic interventions based on standard base excess and serum lactate level could be reliable to improve clinical outcomes in severe sepsis and septic shock patients
Comparar a evolução do “standard base excess” e o nível de lactato sérico entre pacientes sobreviventes e não sobreviventes com sepse grave ou choque séptico reanimados com o “early goal directed therapy”.
Estudo retrospectivo em uma unidade de terapia intensiva de um hospital escola onde sessenta e cinco pacientes com sepse grave e choque séptico foram observados sem intervenções.
Em nosso estudo, a mortalidade na sepse grave e choque séptico foi de 38%. A saturação venosa central de oxigênio nos dois grupos foi maior que 70% depois da reanimação, exceto no segundo dia no grupo dos pacientes não sobreviventes (69,8%). Depois do segundo dia, a saturação venosa central foi significantemente maior no grupo dos sobreviventes (p<0.001). O “standard base excess” foi inicialmente baixo em ambos os grupos, mas a partir do segundo dia a recuperação do “standard base excess” foi significantemente mais importante e linear no grupo dos sobreviventes (p<0.001). Os níveis de lactato foram similares na evolução dos dois grupos.
O “standard base excess” e o lactato são ainda considerados como marcadores prognósticos em pacientes com sepse grave ou choque séptico reanimados de acordo com o “early goal directed therapy”. Outros estudos devem ser realizados com a intenção de demonstrar se intervenções hemodinâmicas baseadas no “standard base excess” e nos níveis de lactato podem ser úteis em melhorar desfechos clínicos em pacientes com sepse grave ou choque séptico. |
